Table 2.

Performance of the ANN model 1 (spectra only) and model 2 (spectra plus anatomical segmentation) in validation data set (796 voxels): area under ROC curve (AUC) and sensitivity and specificity at confidence level of 0.5.

AUC Sensitivity (%) Specificity (%)
Estimate 95% CI
Model 1 0.949 0.909 – 0.990 50.0 (8/16) 98.7 (770/780)
Model 2 0.968 0.937 – 0.999 62.5 (10/16) 99.0 (772/780)

Note: AUC for model 2 is significantly higher than AUC of model 1 (p = 0.03) (15).
